  • the communication part (N) is formed at the point where the front oil passages (P1, P3) and the rear oil passages (P2, P4) communicate, and the air volume distribution door 600 is formed around the communication part (N). It is provided to control the direction and volume of the flowed air, and then distributes it appropriately to the front and rear seats and discharges them.
  • the front seat temperature control door 510 and the rear seat temperature control door 520 are useful because they can simultaneously control the flow path openings of cold and hot air, unlike the conventional vehicle air conditioner.
  • the air conditioner for a vehicle can stably control the discharge temperature and air volume of the front and rear seats by operating four temperature control doors.
  • the temperature control auxiliary door is installed in the vertical direction, there is an advantage of a package reduction in the arrangement of the heater core, and it is easy to secure a flow path.

Abstract

L'invention concerne un climatiseur de véhicule permettant de compléter et de réguler le volume d'air évacué vers des sièges avant et des sièges arrière à travers un composant de porte qui commande un trajet d'écoulement, et permettant de réduire la longueur d'un emballage dans la direction d'un faisceau de chaufferette. Le climatiseur de véhicule présente un passage d'air comprenant : un trajet d'écoulement de siège avant à travers lequel de l'air froid ou de l'air chaud est évacué vers les sièges avant d'un véhicule ; et un trajet d'écoulement de siège arrière à travers lequel de l'air froid ou de l'air chaud est évacué vers les sièges arrière du véhicule, le trajet d'écoulement de siège avant comprenant un trajet d'écoulement de refroidissement de siège avant et un trajet d'écoulement de chauffage de siège avant, et le trajet de siège arrière comprenant un trajet d'écoulement de refroidissement de siège arrière et un trajet d'écoulement de chauffage de siège arrière, et comprenant : une première partie de mélange dans laquelle l'air froid du trajet d'écoulement de refroidissement de siège avant et l'air chaud du trajet d'écoulement de chauffage de siège avant sont mélangés ; et une seconde partie de mélange dans laquelle l'air froid du trajet de refroidissement de siège arrière et l'air chaud du trajet de chauffage de siège arrière sont mélangés.
